Oklahoma defensive back Tre Norwood was expected to be a big part of the Sooners' defensive revamping under new coordinator Alex Grinch.
N0w, Norwood could miss significant time after suffering an injury in practice this week. After Tuesday night's practice, Norwood was seen leaving the practice field on crutches.
ESPN reported that Norwood suffered a knee injury and that his return for this season was in question.
The junior from Fort Smith, Arkansas, started 14 games last season. He played for much of the year as a cornerback but shifted to safety and nickelback late in the season.
